Hi Shyam, Were the peers in a connected state anytime *before*? If yes, then these are the things you can do to troubleshoot and get the cluster back to normal (some of which Neils has already mentioned ): 1. Check if the nodes are reachable.. 'ping <ipaddress>' 2. Check if the glusterd daemon is in an active state in all the nodes.. 'service glusterd status' 3. Firewall issue - flush IPtables on the node which is disconnected.. 'iptables -F' Do let us know if this helps.. Regarding *how* you landed up in this situation, as Atin mentioned, it would be better to be a little specific on the things that you did at your end.

If that works fine, check if you can connect to port 24007 on those systems. This might be a network issue, firewall or glusterd is not running (anymore) on those systems. Sometimes it also helps to check on other systems, and se if the output of "gluster peer status" is different there. Good luck! |
